DESCRIPTION OF THE EMBODIMENTS

In order to describe the ideas and the objects of the present application, the present application will be described in detail below with reference to the accompanying drawings and the embodiments.

As shown in FIG. 1 to FIG. 3, a toothbrush with U-shaped bristles for manually squeezing toothpaste comprises a U-shaped dental sleeve 10 with bristles, a dental sleeve holder 20 disposed in the U-shaped dental sleeve 10, a handle container 40 for accommodating toothpaste, and a hollow insertion shaft 30, a toothpaste hole 21 of the dental sleeve holder 20, and one end of the insertion shaft 30 is connected to the dental sleeve holder 20, and the other end is connected to the handle container 40, and the handle container 40 is provided with a pushing structure 50 for pushing the toothpaste to move into the insertion shaft 30. The toothpaste pushing mechanism 50 pushes the toothpaste in the handle container 40, so that the toothpaste is pushed from the handle container 40 to the U-shaped dental sleeve 10, and the toothbrush could be used, which is convenient to use; the toothpaste pushing mechanism 50 pushes up from the bottom of the handle container 40, so the toothpaste in the handle container 40 could be completely used up.

As shown in FIG. 1 to FIG. 3, the pushing structure 50 comprises a screw 51, a sliding piece 52 and a knob 53, and the screw 51 and the sliding piece 52 are disposed in the handle container 40, and the inner end of the screw 51 and the sliding piece 52 are threaded connection, and the outer end is fixedly connected to the knob 53.
